What Are Oat Flour Sugar Cookies?

Oat Flour Sugar Cookies are similar to regular sugar cookies, but the all-purpose flour is replaced with a healthier alternative: oat flour.

Oat Flour Sugar Cookies are healthy cookies naturally:

• Vegan
• Dairy-free
• Egg-free

Ingredients and Substitutions

It’s very easy to make oat flour cookies with only 3 ingredients.

• Homemade oat flour – you can make your own oat flour from rolled oats, or you use almond flour for a vegan, gluten-free recipe option.
• Liquid sweetener – any refined sugar-free sweetener works well, like coconut nectar, agave syrup, or maple syrup. Don’t swap for granulated sweeteners. The recipe won’t work with brown sugar, coconut sugar, or erythritol.
• Melted coconut oil or vegan butter.

Optional Ingredients

Once you’ve made your first batch of these delicious cookies, you can try changing their taste and texture by adding some optional ingredients such as:

• Baking Powder (1/2 teaspoon)
• Baking soda (1/4 teaspoon)
• Vanilla Extract (1/2 teaspoon).

How to Make Oat Flour Sugar Cookies

Let me show you how you can make these healthy sugar cookies with crispy edges and delicious hearty flavor

1. Start by preheating your oven to 350°F (180°C). Line two cookie sheets with oiled parchment paper. Set them aside.
2. To form a dough, simply stir all liquid and dry ingredients together in a mixing bowl using a silicone spatula.
3. The dough should be sticky but not liquid or dry. If too dry, add more coconut oil or syrup, one teaspoon at a time. If too wet, add more oat flour.
4. The dough is sticky, and you must roll the dough between pieces of parchment paper, or it will stick to the rolling pin. Another option is to form cookie dough balls and flatten them with your hand palm on the cookie sheet. This is much easier than using cookie cutters that tend to stick to the dough.
5. Start by oiling two pieces of parchment paper and placing the dough in the center of the first piece.
6. Then, place the other piece on top of the dough, and using a rolling pin, roll the dough encased between the oiled pieces of parchment paper until 1/4-inch thin.
7. Cool the baked cookies down on a cooling rack at room temperature.
8. When they reach room temperature they are ready for decoration.

Cookie Dough Texture

This cookie dough is very different from classic flour-based sugar cookie dough. It’s grainy, darker, chewy, and sticky. Depending on the thickness of your oat flour you will have to adjust the dough by adding more oat flour to handle the dough easily.

Decorating

You can decorate the gluten-free sugar cookies using my vegan royal icing recipe, simply made of powdered sugar and water. Another option is to serve them plain or with some of the frosting below:

• Chocolate protein frosting
• Cashew frosting

Feel free to add some food coloring drops to the icing to create a range of colorful sugar cookies. Once you’ve iced the cookies, you can add sprinkles, vegan chocolate chips, or even a pinch of salt.

Storage Instructions

These vegan oat flour sugar cookies can be stored in a cookie jar at room temperature for up to 1 week or frozen for later up to 3 months. Thaw them at room temperature before eating.

Allergy Swaps

If you are allergic to one of this sugar cookie recipe’s ingredients, you can make the following substitutions:

• Oat Flour: if you are allergic to Oat Flour, you can swap it for Almond Flour.
• Coconut Oil: if you are allergic to coconut, use vegan butter.
